INVESTOPEDIA EXPLAINS 'Stress Testing'

Stress testing is a useful method for determining how a portfolio will fare during a period of financial crisis. The Monte Carlo simulation is one of the most widely used methods of stress testing.

A stress test is also used to evaluate the strength of institutions. For example, the Treasury Department could run stress tests on banks to determine their financial condition. Banks often run these tests on themselves. Changing factors could include interest rates, lending requirements or unemployment.
